Important information:
1.1 About these operating instructions:
All the lattice extensions described in these operating instructions can be obtained as additional
equipment.
Validity of these Operating Instructions:
- These operating instructions only apply to lattice extensions which were de- livered by Deutsche
GROVE GmbH. - In addition, for the operation of the truck crane with a lattice extension de- scribed in these
operating instructions, all details in the included Operating instructions for the GMK 7450 for
which the lattice extension was delivered, are applicable.
Prerequisites for assembly and operation:
The lattice extensions described in these operating instructions may only be operated together with
a GROVE truck crane GMK 7450 whose serial num- ber is identical with the serial number that is
marked on the lattice extensions.
Safety instructions:
The operation of GMK 7450 with one of the lattice extensions described in these operating
instructions is subject to:
β the basic safety instructions to be found in the subsequent section Basic safety instructions
and
β the safety instructions contained in the supplied operating instructions of
GMK 7450.
